Re: [libvirt] [PATCH 01/19] libxl_migration: Resolve Coverity NULL_RETURNS

Coverity noted that all callers to libxlDomainEventQueue() could ensure the second parameter (event) was true before calling except this case. As I look at the code and how events are used - it seems that prior to generating an event for the dom == NULL condition, the resume/suspend event should be queue'd after the virDomainSaveStatus() call which will goto cleanup and queue the saved event anyway.
